I received this question:

Hello.

We have been doing your dvd year 1.  Quiz 16 question 1 says “All prepositions are followed by ablative nouns“. True or False?  The answer says false. We have several charts  saying that ablative is the object of the preposition.  So I thought that the answer would be true.  We are a little confused.  Could you help?  

Thank you so much!
